How many physics jobs are run per BOINC Work Unit?

The average CERN job run time is around 1 hour, including the delays between downloading/uploading libraries, results, etc.

So, taking into account that each BOINC Work Unit will be running in your computer for 24 hours, on averageeach BOINC Work Unit will simulate in your virtual machine around 20 CERN physics jobs, or about 2 million collision events.
